METHOD OF CONNECTING PLATES OF ELECTRIC CONDENSERS AND THE LIKE TO THEIR SUPPORTS.

Application filed ma 12, 1927, Serial No.

The object of the present invention is to provide means whereby the parallel, spaced plates of variable electric condensers and the i like can be secured to their supports in a convenient and reliable manner, and the invention consists in forming each support with slits for' the reception of the plates and with a channel which intersects said slits for the reception of a binding pin adapted, when driven through the channel, to press ofl flanges from the plates and clamp said flanges to the channel Walls.

' Fig'. 1 of the accompanying drawings represents a plan view of the fixed electrode of a Variable electric condenser, and

Fig. 2, a section of the same taken in the longitudinal direction of the supports, one side of the same being in process of comple tion.

The supports 2 to which the parallel and spaced plates 1' of a variable electric condenser or the like are secured, are formed with slits 3 for the reception of the plates, For

securing the plates to the supports, the'latter are provided with channels 4 which intersect the slits 3 for the reception of binding pins 5 adapted, when driven through the channel, to press off flangesfrom the plates and clamp said flanges securely to the channel'walls. In the arrangement shown, the channels 4 are in the form of bores, and the plates are formed with apertures 6 which are coaxial with the bore and which guide the binding pins and ensure a correct positioning of the plates rela- 5 tive to one another and to the supports. The binding pins, which are smallerthan the bores and larger than the apertures 6, may be tubular as shown. 7 Connected together in this fashionthe plates 40 and the supports will be securely 'nterlocked,

and a perfectly rigid structure will be obtained. Perfect electric continuity-between the different plates is also ensured, and as the fastening method is exceedingly simple, it lends itself to the construction of a condenser which is cheap and yet of the highest quality.

The supports 2 may be made of metal, for instance aluminium, in which case the terminal screw can be applied to some part of the supports. However, the supports may be made of insulating material, such as vulcanite or the like in which case the terminal screw is connected to one of the binding pins 5. i
